A question on how this add-on works about blender_spreadsheet_import

[simonbroggi]

Hello,
It depends on how you want to use the data.
The add-on creates a new object with geometry, and imports your data into custom attributes in the Point/Vertex Domain of the Mesh Component of that geometry.

Some Blender geometry theory:
Geometry in Blender can contain Mesh, Curves, Point Clouds, Volume Grids and Instances. These data containers are called Components. The mesh component can contain Vertices, Edges Faces and Face Corners. These are called Domains. The Vertices are sometimes also called Points.

To use the data with geometry nodes, I like to drag & drop it into an existing geometry node tree, on another object.

Here's a screenshot that might help. Note that I pinned the spreadsheet editor (top left) on the imported "DataFromCSV", so that I know what kind of data I am working with even when I have another object selected. The Object I create the Geometry Nodes modifier on here is just a default cube moved up one unit in edit mode such that the origin is on the 'ground'.

It's probably important to understand the concept of Fields in geometry nodes to work with this.

I hope that helps!
Best, Simon

oh, and the quick reply to your question:
1: No
2: Probably the object that the importer generated
